Introduction
Starting an aquarium brings tranquility and beauty to your home, but improper care risks fish health. This guide simplifies freshwater fishkeeping with science-backed methods, avoiding common beginner pitfalls.

1. Choosing Your Aquarium

• Tank Size: Opt for 20+ gallons; smaller tanks amplify toxin buildup. Example: A 20-gallon tank supports 6 small fish (e.g., guppies).

• Location: Place away from direct sunlight/windows to prevent algae blooms and temperature swings. Stable environments reduce stress.

• Equipment Essentials:

  • Filter: Canister or hang-on-back (e.g., Fluval C2) for 5x hourly water turnover.

  • Heater: Adjustable 50W heater for tropical species (75–80°F).

  • Substrate: Rinse gravel/sand thoroughly before adding.

2. The Nitrogen Cycle: Non-Negotiable Setup
Before adding fish:

• Add dechlorinated water and ammonia source (e.g., fish food).

• Test water daily with API Master Kit. Target levels:

  • Ammonia: 0 ppm

  • Nitrites: 0 ppm

  • Nitrates: <20 ppm

• Cycle takes 4–6 weeks. Speed up with bacterial starters like Seachem Stability.

3. Selecting Beginner-Friendly Fish

4. Feeding & Nutrition

• Frequency: Twice daily, portions eaten in 2 minutes.

• Diet Variety:

  • Flakes/pellets (e.g., Hikari Micro Pellets)

  • Weekly supplements: Frozen brine shrimp/bloodworms.

• Avoid overfeeding: Excess food decays into ammonia.

5. Maintenance Routine

• Weekly:

  • Test water parameters.

  • Scrape algae with magnetic cleaner.

• Biweekly:

  • Replace 25% water using a gravel vacuum.

  • Rinse filter media in tank water (never tap).

• Monthly: Trim live plants; check equipment.

6. Health Monitoring
Common issues and solutions:

• Ich (White Spots): Quarantine fish; raise temp to 86°F + medication.

• Fin Rot: Improve water quality; use antibacterial treatment.

• Prevention: Quarantine new fish for 2 weeks.

Conclusion
Patience transforms beginners into successful aquarists. Consistent care prevents 90% of fish diseases. Start small, document water tests, and expand gradually. Your thriving aquatic ecosystem awaits!
